Technical Abstract:
The US law requires flame resistant properties on apparel or house hold items to prevent or minimize the fire damage. The objective of this research was to develop a non-halogenated flame retardant for application onto cotton fabrics. These treated fabrics can then be used in clothes or beddings to increase their flame resistance. Here describes the synthesis, characterization, and flammability of a water-soluble, non-halogenated organophosphorus flame retardant (FR), dimethyl-[1,3,5-(3,5-triacryloylhexahydro)triazinyl]-3-oxopropylphosphonate. The FR was synthesized in a one-step reaction bounder mild conditions and its structure was characterized. The finishing condition to achieve a covalent bond between the FR and fabrics was optimized, and the FR capability of the treated cotton was investigated by LOI, vertical flame tests, TGA, and MCC tests. This study showed that fabrics treated with the FR are effectively flame resistant, and the FR property is enhanced by covalent bonding of the FR to fibers.
